Specification of Letters Patent. Application led May 14,1904. Serial No. 207,941.

Patented April 17, 1906.

l'o a/ZZ whom, it may concern:

Be it known that I, HAMET BROWN, a citizen of the United States, and a resident ofthe city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Conveyer, of which the following is a full, clear, and exact description.

My invention relates to a conveyer of that class known as vertical7 conveyers which is provided with a series of horizontal pans or shelves for carrying the material to be transferred.

The principal object of the invention is to provide automatic means for depositing the material upon the desired floor of a building A whther the material is being raised or lowere g Certain other subsidiary objects of the invention will be disclosed in the course of the following description.

Reference is to be had to the accompanying, drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the iig- .A UTGS.

Figure 1 is a verticalusectional view of a building, showing an elevator-shaft with a referred form of my invention located therein. Fig. 2 is a horizontal sectional view on the line 2 2 of Fig. 1. Fig. 3 is a fragmentary view in perspective of a portion ofthe device, and Fig. 4 is' a fragmentary view of parts shown in Fig. 1 on an enlarged scale.

In the drawings, 11 represents the'endless' chain or belt conveyer operated and 'con- "trilled by means of sprocket-wheels 12. The

conveyer 1s provided with a series of pivoted pans or shelves 13, each of which has a-projecting arm upon one side thereof, Ihaving a roller 14 designed to pass alon in contact with a track 15 on one side of t e conveyer and a similar track 15 upon the other side. These two tracks are so arranged as to keep the shelves or pans in horizontal position throughout their travel with the conveyer except at such places as it is desired to deposit the material being transferred. For the purpose of permitting this discharge of the material osets 16 16 are made in both tracks. 4It will be obvious that when the rollers 14 come to a place where there is no straight track and they are obliged to follow these offsets on account of the weight of the material on the pans the pans will be allowed to assume an inclined position and discharge their contents, as shown, on the third iioor at the left and on the first floor atthe ri ht in Fig. 1. It is desirable, however, that t e device be arran ed in such a manner that the pans will not gfie moved out of the horizontal position except at the desired floor or fioors. For this purpose ivotedA plates 17 17 are provided at each oor and on both sides of the conveyer. Each of these plates is rovided with a bar 18 18', no two of the ars being located in the same vertical position. Each of the plates is also provided with a sectionof track 19 19', designed when the plates are brought to a position against the track 15 15 to close the gap made by the oset 16 16', and conse uently furnish a continuous track forthe ro er 14. These pivoted plates are normally held inl such positlon as to cause the track-sections 19 19 to close the ga s formed by the offset portions of the tracks y means of cords, ropes, or chains 20 and counterweightsQi. In order to provide for automatic-a ly swinging these plates out from this position, sothat the pans will be caused to discharge their contents at the desired floor, an adjustable lug 22"is attached to each pan. These lugs will be so adjusted as to come in contact with the bar 18 or 18 at the floor upon which it is desired to discharge the material. A s illustrated in Fig. 3, the lug 22 upon coming in contact with the bar 18 will force the plate 17 .u on its pivot away from the track 15 and al OW the roller 14 to ass into the offset part, so that the pan wi be caused to-drop backwardly on its pivot and discharge its contents. Upon passing down upon the other side of the conveyer a similar operation will'itake place-at the desired floor. Of course the lug l,22 will pass by the bars on the plates on the other .floors without interfering with them, and continuous tracks will be furnished for the roller 14 by means of the sections 19 `and 19.

In order to provide for the operation of the device by hand, a flexible connection 23 and 23 is joined to each of the plates 1.7 and 17 These connections pass over pulleys 24 and 24 and reach down to aposition where they can be worked by the operator, so as to remove the plates 17 and 17 from their positions next to the tracks at any desired place and time, thus causing the discharge of the material upon the desired floor.

Upon the left-hand side of the shaft illustrated in Fig. 1, or, in other words, upon the ascending side of the conveyer, are chutes 25 IOO IIO

AIo

u on each floor, and to thein are pivoted p ates 26. It will be seen by this construction that the pans ascending will when in horizontal position cause the plates 2G to be moved on their pivots, as shown vin dotted lines at the bottom of the figure, and that they will naturally fall back by gravity after the pans have passed; but, as shown at the top of the figure, when the pans are caused to discharge their contents the plates 26 will project toward the pans far enough to receive all of the material discharged therefrom. Upon. the descending side of the conveyer, however, such a simple arrangement could not be placed, and consequently the chutes 25', although having the pivoted plates 26 similar to the plates 26, are necessarily provided with other operating means, which comprises a lug 27, attached to each plate 26', and a pivoted lever 28, pivotally attached to each lug. This lever 2S is in turn attached to a reciprocating rod 29, which is designed to be operated by the rollers 14 When they enter the offsets at which the ends of the rods 29 are located. This operation causes the levers 28 and the lugs 27 to move in such a manner as to make the plates 26 assume the position shown on the first floor at the right in Fig. l while the pan is dumping. Immediately after the pans pass, the weight, 30, carried by the plate 26', returns the chute to normal position, as shown on the second and third floors. On those floors at which it is not designed to have the pans discharge their contents the rollers 14 not entering the offset 16 will not come into contact with the ends of the rods 29, but will permit them to remain in their normal position while the pans pass.

Although I have described a particular construction which illustrates my invention, it Will be obvious that the latter may be embodied in many other forms and that many modifications may be made therein. It will also be obvious that a mere reversal of the construction illustrated would be within the scope of my invention. For example, the offsets 16 could be on the opposite side of the track, in which case the pans would be tilted upwardly and the conveyer could be loaded while going up on the left side. This arrangement could be applied also to the righthand side.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An endless conveyer having pivoted pans, a track therefor, a series of offsets in said track, a pivoted plate located adjacent to each oset, a section, of track on each plate, means for holding said plates against the track, comprising a counterweight, and means for temporarily removing said plates from said tracks.
